Abstract

The species Arabidopsis halleri, an emerging model for the study of heavy metal tolerance and accumulation in plants, has evolved a high level of constitutive zinc tolerance. Mapping of quantitative trait loci (QTL) was used to investigate the genetic architecture of zinc tolerance in this species. A first-generation backcross progeny of A. halleri ssp. halleri from a highly contaminated industrial site and its nontolerant relative A. lyrata ssp. petraea was produced and used for QTL mapping of zinc tolerance. A genetic map covering most of the A. halleri genome was constructed using 85 markers. Among these markers, 65 were anchored in A. thaliana and revealed high synteny with other Arabidopsis genomes. Three QTL of comparable magnitude on three different linkage groups were identified. At all QTL positions zinc tolerance was enhanced by A. halleri alleles, indicating directional selection for higher zinc tolerance in this species. The two-LOD support intervals associated with these QTL cover 24, 4, and 13 cM. The importance of each of these three regions is emphasized by their colocalization with HMA4, MTP1-A, and MTP1-B, respectively, three genes well known to be involved in metal homeostasis and tolerance in plants.

摘要

拟南芥（Arabidopsis halleri）是研究植物对重金属耐受性和积累的新兴模式植物，它已进化出高水平的组成型锌耐受性。利用数量性状基因座（QTL）定位来研究该物种锌耐受性的遗传结构。从一个高度污染的工业场地获得的拟南芥（Arabidopsis halleri）亚种哈勒氏拟南芥（A. halleri ssp. halleri）及其不耐受的近缘种琴叶拟南芥（A. lyrata ssp. petraea）产生了第一代回交后代，并用于锌耐受性的QTL定位。使用85个标记构建了覆盖大部分拟南芥（A. halleri）基因组的遗传图谱。在这些标记中，65个锚定在拟南芥（A. thaliana）中，并与其他拟南芥基因组显示出高度的共线性。在三个不同的连锁群上鉴定出三个效应相当的QTL。在所有QTL位置，哈勒氏拟南芥（A. halleri）的等位基因都增强了锌耐受性，表明该物种对更高锌耐受性存在定向选择。与这些QTL相关的两个LOD支持区间分别覆盖24、4和13 cM。这三个区域分别与HMA4、MTP1 - A和MTP1 - B共定位，强调了这三个区域各自的重要性，这三个基因是众所周知的参与植物金属稳态和耐受性的基因。
